Introduction Recently acquired by Fingal County Council, Drumanagh promontory fort is a highly sensitive multi- layered archaeological landscape. Recorded by 19th century antiquarian T.J. Westropp, as ‘one of the three largest promontory forts with straight works so far recorded in Ireland’ Drumanagh is also one of four coastal promontory forts in Fingal. It has long been the subject of interest due to the recovery of Romano-British material from the site and has been characterised in the press and public imaginations as the place where the Romans may have landed. This study compiles the accessible historical, archaeological, folkloric, and cartographic evidence together in order to provide a comprehensive narrative for the use of the site and inform its future protection and management. The document was prepared by Christine Baker, Community Archaeologist, Fingal County Council. Image: Nua Photography © Drumanagh Conservation Study & Management Plan 2018 - 2023 1 2 Study Area 2. Study Area Drumanagh promontory fort is coastally located 0.6 km south of the village of Loughshinny, approximately 1.8 km north of the village of Rush and 0.5 km east of the R128 Rush to Skerries road. It is accessed to the south by a laneway and to the north along a cliff pathway. Approximately 6 km to the south-east is the island of Lambay. Fig. 1: Location Map The site consists of a headland of c.46 acres defended by a series of earthworks (L.350m), except where they curve inwards towards the southern limit. The relatively flat promontory is delimited to the west by three closely-spaced earthen banks and ditches. A small stream flows along part of the inner ditch to the southern cliff edge. A number of gaps occur along the ramparts, one or more of which may represent an original entrance. The site is bounded to the west by the townland boundary with Ballustree and to the south by the townland boundary with Rush. The underlying geology consists of glacial till overlying Lower Carboniferous limestone. The soils are Grey-Brown Podzolics, with associated Gleys. 2 Drumanagh Conservation Study & Management Plan 2018 - 2023 Methodology 3 3. Methodology This Conservation Study involves a process that ‘seeks to guide the future development of a place through an understanding of its significance’ (Kerr 1999, 9). By defining the setting and context of the monument; analysing its cultural and material significance and assessing its vulnerability, the process outcome will be a policy-based guidance document. The study is conducted with the protection and public enjoyment of the monument as its central point of reference. A three-phased approach was undertaken, comprising desktop research, field-recording and photographic survey, and report compilation. 3.1. Phase 1-Information Gathering The desktop or information gathering-stage included an examination of available documentary sources, cartographic evidence, folklore, images and illustration of the site.
